Hi

I am getting a type mismatch error on trying to call one function from another. I am passing three strings
The two procedures are below....

Sub Import_Tables_And_Convert_to_Internal_Table()

     Call Import_Table_from_another_AccessDB ("G:\GFI_LoanTrading_Support\Production_Applications\Leveraged_Fin_Database\Application\Leverage_Finance_Rec_Tool.mdb", "t_LNK_BC_Fidessa", "t_LNK_BC_Fidessa")
 
     
End Sub

Sub Import_Table_from_another_AccessDB(ByVal sPathAndFile As String, ByVal sSourceTable As String, ByVal sDestinationTable As String)

    DoCmd.TransferDatabase acImport, sPathAndFile, acTable, sSourceTable, sDestinationTable

End Sub

2nd parameter needs database type
e.g.

    DoCmd.TransferDatabase acImport, "Microsoft Access", sPathAndFile, acTable, sSourceTable, sDestinationTable

I assumed when not specfying the database type, it picks the default. The default one may not be "Microsoft Access" in this case. Pete would u know?

I just tried this as a test as I got an error, but it's not a datatype mismatch
"the type isnt an installed database type or doesnt support the operation you chose"

So for me "Microsoft Access" is not the default type.

yes I do have to specify that. Is it perhaps a Microsoft Windows setting that may be on my bank's network?

No, I wouldnt think so. I think u just have to specify the database type. The help does not mention any type of Default value, if there was, it would of mentioned it.

the datatype mismatch error was due to acTable

acTable is numeric and has a value of 0
u was passing in sSourceTable (string) when u should of been passing acTable (numeric) due to parameters misaligned.

Adding the 2nd comma aligned the parameters so that removes your original error but it appears u still have to specify the database type.

Help says states that the database type parameter is optional and that Access is the default type .
This appears to be a travesty of the truth as far as A2003 goes.  I haven't tried on anything else.
Can't find anyone reporting it as a problem, which is surprising.

Maybe significantly, MSDN does not state it is optional, although still says Access is the default type ( ? which means what, if it is not optional)

Anyway, it appears the database type is necessary.

Pete

Which help are you looking at Rocki?

A2003 help file =:

DatabaseType   Optional Variant. A string expression that's the name of one of the types of databases you can use to import, export, or link data.

Types of databases:
Microsoft Access (default)
Jet 2.x
Jet 3.x
dBase III
dBase IV
dBase 5.0
Paradox 3.x
Paradox 4.x
Paradox 5.x
Paradox 7.x
ODBC Databases
WSS

dunno now, bugger, what the hell was I reading. I missed the Optional variant bit as I just saw that now.

So if Access is the default why aint it working then, a bug perhaps or help files incorrect?
